SWITCH STAND.

Original application filed May 8, 1918, Serial No. 261,629, now Patent No. 1,384,488, issued July 12, 1921. Divided and this application filed May 9, 1921. Serial No. 468,004.

To all I107mm t may concern.'

Be it known that l, NEIL E. SaLsioH, a

citizen of the United States.` and residing at Bethlehem, Northampton County, Sta-te of Pennsylvania, have invented certain new and useful improvements in Switch Stands, ot which the following is a speciiication.

The present application which is a divisionoi:l my application 261,629 tiled May S, 1918,'now Patent No. 1,384,488, issued July 12, 1921, relates to railroad switch mechanism, and more particularly to switch stands therefor. y

The principal objects of the invention are to provide a device of the class mentioned which comprises a minimum number ot sim'- ple parts and includes a target mast; to provide `a dependable mechanism and one which is protected from the weather and properly lubricated. A further feature of the invention consists in the combination with the above features of an adjustable arm for transmittingmotion to the switch operating` rod.

Other objects and features ot novelty will be apparent from the description taken in connection with the drawings in which.:

Fig. 1 is a top plan view of a switch stand constructed in accordance with the present invention Fig. 2 is a iront elevation of the stand shown in Figure 1;

Fig. 3 is a sectional elevation taken substantially on the line 3 3 of Figure 1;

Fig. 4 is a sectional plan view taken sub stantially on the line 4-4 ot Figure 3;

Fig. 5 is a sectional elevation similar to Figure 3 illustrating another form of the invention; and i Fig. 6 is a sectional plan view taken sub-V stantially on the line 6-6 of Figure 5.

Referring to the drawings the numeral 2O indicates thebase plate of the switch stand, which is shown as substantially reetangular as viewed in plan. Substantially centrallylocated on the plate is a raised portion forming a. housing a1, which as shown in Figure 3, has an open bottom and is also open at one of the lateral edges oit the plate. The actuating lever` 22 is piv oted at the iront of the housing. as by means o't' the spindle rotatively mounted in the bore 24. In order to` aidin holding lthe switch against displacement weight 25 may be secured to the end of the lever in any suitable manner, as by casting the weight thereon. The lever 22 is designed to occupy the position shown in Figures 1 and or, to be thrown over to a position oppo- `tively y hold the f lever against displacement.

` The swinging motion of the lever 22 is converted into substantially rectilinear movement of the switch operating rod 29 by mechanism disposedwithin the housing 21. As shown in Figure 3, the top wall of the housing is provided with the bosses 30 and 31 having the bore 32 in which is rotatively mounted the sleeve-like hub 33 of a bevel gear 34, the latter being disposed within the housing` and the hub 33 being long enough to project above the boss 30. A target mast 35 is disposed in the axial bore 36 of the hub 33, and secured thereto for rotation therewith in any suitable manner as by means ot the taper pin 37. As clearly shown in Figures 3 and 4, the vsegmental bevel gear 34 is provided with a del'ieiiding lug orear 3S disposed substantially coaxial with the axis of rotation of the gear. Thisl lug is provided with a threaded bore in which is disposed the threaded eye bolt 39, with its axis substantially at right angles to the axis of the gear 34. The pivoted end of the eye bolt 39 is connected to the switch operating rod 29 by the pin 4() and transmits motion from the gear 34 to the said rod. It will be noted that the rod 29 operates through the open side ot the housing and is disposed at an elevation above the bottoni 'of the base plate.

The spindle 23 projects into the housing 21 and has a square end 41 on which is mounted a segmental bevel pinion 42, a cotter pin 43 preventing axial movement of this pinion in one direction on the spindle. The arrangement ot the gears is such that the gear 34 is -disposed above the pinion 42 and is supported by the latter against downward axial movement. Because ot this arrangement iio devices are required to hold the gear against downward movement, and the entire construction of the switch stand is very much simplified.

For the purpose oi' lubricating the moving Figures' and', the target mast provides the bearing for the upper bevel gear. Thus vthe housing 2l is provided with a downwardly 'extending boss 3l around the bore 32. The stand'is also provided with an arm formedwitha bore 51 aligned with the bore'32, this arm `being disposed below the gearing and secured to the stand, preferably being integral*therewith. The. target mast 35 is rotatively mounted inthe bores 32 and l andthe upperbevel gear 34C is mounted on the mast' being secured thereto by the pin 37. The gear 34 is provided with'a lug 38 offset from the axis of the gear andtarget mast, this lug carrying the threaded eye bolt 39, the axis otwhich is otlset from the axis ofthe gear and substantially perpendicular thereto. The free end ot" the eye bolt is pivotally secured tothe actuating rod 29, as by means of a pivot pin 40. The gear 34 is provided with an oil reservoir lla, as described in connecten with the form of Figure 3. This gear is also op# erated in the same manner and downward axialinovemcnt prevented by the pinion ft2. It will be observechas the target mast `is cured tothe gear Bil', the mast in turn is secured against downward axial movement.

Having thus described the invention what is claimedas new and desired to be secured by Letters Patent is: y

l. A switch 'stand including in combination, a base plate having a housing-the top wall of which is toi-ined with a vertical bearing, a bevel gear 'within said housing having a sleeve rotatably disposed in said bearing whereby said gean is mounted Jtor rotation about a vertical axis, a target mast secured toy said gear, a bevelpinion meshing with said gear disposed below the latter and means to turn said pinion.

2; A switchstand including in combinaan axial projection within the housing, an

eye boltthreaded in said projection at right angles to the axis ot the gear adapted to be connected tothe switch rod, a bevel pinion i meshing with `said said pinion,

Ll. A switch sta-nd including in combina.- tion, a base plate having a housing, albevel gear within said housing mountedifor rotationva'bout a vertical axis, the hub thereof havin-g a lug, an.V eye boltv threaded in vsaid lug within the housing the axisot said bolt being substantially horizontal, said bolt adapted tor connection to the switch rod, a bevel pinion meshing with saidgear, and means to turn said pinion;

5. A switchstand including in combination, a base plate having an integral housing closed at the top and open at one side, a bevel gear within the housing mounted for rotation about a vertical-axis atarget mast secured to said gear and projecting through the top ot the housing, a pinion disposedbelow said" gear in mesh therewith and holding `the gear against axial inoveinentlin one direction, a bolt threaded to the gear hub with its axisat right angles to the gearaxis and adapted for connection to an operating rod through said open side, and means torotate said pinion.

6. A switch sta-nd including in combination, a base plate having a housing the top wall of which is 'formed with a vertical bearing, a bevel gear within said housing having a sleeve rotatably disposed inv said bearing wliereby said gear is mounted'for rotation about a vertical axis, a bevel pinion meshing with said gear disposed below the latter and means to turn said pinion.
